Twenty questions were designed concerning elementary knowledge of high alert medications, storage management, medication issues and risks. In order to understand the knowledge level and education status of high alert medication, a convenient survey was conducted among 300 medical staffs in Tianjin. Medical staff＇s average score of high alert medication knowledge was 12.43±0.27, and the average scores of elementary knowledge of high alert medication, storage management, medication issues and risks were 3.38±0.11, 2.46±0.14, 3.17±0.11 and 3.41±0.12 respectively. Occupation（F=4.86, P=0.003）, education background（F=5.57, P=0.019） and professional titles（F=13.44, P≤0.001） contributed to the high alert medications knowledge scores. Currently, the most important channel to obtain high alert medication knowledge was hospital files or administrative rules, and clinical pharmacist seminars were the most popular education form. It was suggested that the high alert medication knowledge level of the medical staff needs to increase, and it might benefit from targeted, systematic and diverse training to the medical staff working in the different circulation nodes of the medications. Further research to develop and validate the instrument is needed.展开更多
